Abstract/OtherAbstract:
|
An efficient Sonogashira coupling of terminal alkynes and styrenyl bromides has been achieved under the catalysis of hydroxyapatite-supported copper (I). The trans-styrenyl bromides produce the usual trans-en-yne products, whereas the cis- styrenyl bromides lead to unsymmetric 1,3-diynes by the cross coupling of terminal alkyne and the alkyne generated from the cis-styrenyl bromide. A series of trans-en-ynes and unsymmetric 1,3-diynes have been synthesized by this protocol. |
